We are to believe that this person unwittingly rode their bike into wet concrete, kept riding it for about ten feet, realized they were in concrete, and then just ditched the bike. I feel like if you've done it once, you might as well yank the bike out and try it again to see if you can go further. You already messed up the concrete. You might as well mess it up even more. Let's call it job creation. If you screw up public works, the city has to hire more people to fix what you screwed up.
Now this just looks like some kind of weird art installation. People can sit on a bench nearby and argue over the true meaning of the piece. Is it trying to symbolize how difficult it is to move ahead in this world?
